So, As a WvW Vet and a Commander on and off over the years, let me just say this.I first off lead a group that accepts everyone. This is because we are a group of many many groups made up into one. We run later at night so it is imperative to condense numbers of players to fight off the large groups we are often hit with. However, we are fun oriented, not a serious group and mostly looking to hold things for the server and take things for them. A serious group would need to dedicate itself to WvW metaclasses, as that is what they will end up fighting against. It's not so much that theirs an open squad space I should be in it, its more like adding you to the squad will be viewed (this is not my personal opinion just a general belief out there) as weakening it against other squads that are using the particular skills needed to fight each other. Classes with large amounts of area damage, good healing support are what every squad is going to generally lean towards and unfortunately Rangers/soulbeasts have been more of a roaming class (small scale fights, single player damage oriented) for a long time now. The Soulbeast was close to getting into squads with stances but then things just changed and it just didn't become viable compared to other classes that could do everything better in large scale fights. I am sorry your struggling with this side of WvW you are a valuable resource to the game regardless of what you play. New players or long term that stick around are what is needed to keep the flow of the game. Some servers are widely known for a very elitist mentality and my only suggestion here is to, find a commander that is more open to all classes to follow or look for a server with a different attitude about things where there maybe more commanders willing to snap you up.
